摘要

An evidence them based uncertainty quantification method is presented for robust design. Differ from classical robust design which focused on aleatory uncertainties of design parameters, epistemic uncertainties are also take into account in this paper. By using Dempster-Shafer's integrated framework to characterize both aleatory and epistemic uncertainties of system design parameters, the propagation uncertainties to design objectives of system is investigated. Finally, an example is introduced to illustrate the procedures of our approach.
